摘　　要：以"红富士"苹果为试材,对宁夏新华桥果园、河东陶林园艺场、青铜峡广武、中卫彩达村及中宁鸣沙5个苹果产地的土壤养分状况、果实品质进行了调查分析。结果表明:5个苹果产地的土壤有机质、速效氮缺乏,速效钾含量丰富,速效磷含量中等;果实品质因子中以果实硬度、有机酸、可溶性固形物、单果重与土壤营养因子速效钾的相关性最明显,其中可溶性固形物与速效钾呈极显著负相关,单果重与速效钾呈显著负相关。Taking ‘ Red Fuji ’ apple as materials,the soil nutrient status and fruit quality in Ningxia 5apple production areas were investigated.The results showed that in 5apple production areas,it was poor in organic matter and available N,rich in available K content,and available P content was the medium state,fruit quality factors of fruit firmness,organic acid,soluble solids,single fruit weight were correlated most with the soil nutrient factors of available K,soluble solid of the fruit was negatively correlated significantly with available K,the weight of single fruit was negatively correlated significantly with soil available K content.
